움파룸파가 만든 3D프린팅 제트엔진

2015년 7월 22일

영화 에 나오는 움파룸파 족이 비행기를 만든다면 어떨까? 크기는 일반 항공기보다 작지만 이들에게 어울릴 만큼 기술적으로 뛰어난 혁신적인 제트 비행기가 되지 않을까. 최근 GE의 엔지니어들은 3D 프린팅 기술을 이용하여 작은 제트엔진을 만들었다. 하지만 귀여운 크기와는 달리 이 엔진의 분당 회전수(RPM)는 무려 33,000 에 이르고 있어, 제트엔진이라는 이름에 손색이 없다.

부수고 으깨고 날려버린다! GE의 철학

2014년 10월 2일

상상을 현실로 만드는 기업 GE의 철학은 무엇일까? 사람들이 GE라는 글로벌 대기업에 대해 가지고 있는 선입견과는 달리, GE는 엉뚱한 아이디어와 수많은 실패 위에서 이뤄졌다. 한없이 뭔가를 부수고 깨뜨리고 날려버리는 GE의 과격한 실험실을 엿본다.

Wind, meet water. In Germany’s Swabian-Franconian Forest, you’ll find the world’s tallest (584 ft) and first-ever wind turbines integrated with pumped storage hydroelectric power. So how does it work? At the base of each wind turbine sits a reservoir. Water flowing downhill from the reservoirs will power the hydro plant when electricity is needed. When there’s an energy surplus, the hydro power will push the water back up the hill to the reservoirs, where it will act as a giant battery for the wind turbines. So no matter if the wind is blowing or not, electricity will always be flowing
This Ultra Performance Heat Exchanger is a perfect example of how small parts can make a HUGE difference. Still in development, the additively manufactured compact heat exchanger is printed with a high-temperature capable, crack-resistant nickel superalloy that will be able to withstand temps that exceed 1,650°F at pressures >3,600 psi. Good thing, too, because it’s headed straight for the inside of a gas turbine, where it’s projected to deliver a 4% improvement in thermal efficiency for supercritical C02 power cycles while improving power output and reducing emissions. Cleaner, more efficient power generation here we come.
Spooky season is here, but don't let your annual mammogram scare you. Nearly 30% of women in the U.S. admit to skipping breast screenings out of fear. That's why @gehealthcare engineers decided to better the experience with a mammography system designed by women, for women. Melding comforting design with cutting edge technology, the Senographe Pristina aims to humanize the process for patients, technicians, and radiologists. #BCAM #Mammography #breastcancerawareness
Colder weather is on the way. If you’re in Winnipeg, Canada, that means ice testing is too. There, @geaviation test engines are pummeled with sub-zero winds and ice. The harsh conditions on the ground make sure engines are ready to face the elements in the air. #AVgeek #jetengine #engineering
Slice into an additively-made part from @geadditive and you’ll see geometries once thought impossible with traditional manufacturing methods. Why the hype? Engineers can now find greater strength and efficiency through design. #engineering #additive #3Dprinting #manufacturing
